projects to digitize and make available the world's ancient manuscripts that have long been unreadable. Click here to read her article: The Next Age of Discovery. (Wall Street Journal, 8 May 2009).

"Archivists at the Walters Art Museum in Baltimore used multispectral imaging to read this palimpsest, or text that had been scraped off and written over by a later scribe. The text had been covered up by a 13th-century monk who scraped the parchment with pumice and used the pages to write a prayer book. Multispectral imaging revealed a hidden mathematical treatise by the Greek mathematician Archimedes (above)."

Universities across the country: University of Kentucky, Brigham Young University, Oxford, British Library, Library of Congress, St. John's Abbey & University in Minnesota, Center for the Study of New Testament Manuscripts (Texas), University of Michigan, Berkeley, Columbia University are all working to preserve the world's oldest records. They are harnessing 3-D X-ray scanning, NASA multispectral imaging and the latest tools to digitize and preserve the world's oldest manuscripts.

These projects have saved thousands of manuscripts that were otherwise unreadable and that were slowly deteriorating.
